Which of the following is not permitted for supervising station alarm systems?

• A. Delaying power supply failure signals transmission for more than 10 minutes
• B. Transmitting power supply failure signals immediately on failure
• C. Requiring a manual reset for all failures
• D. Transmitting only during business hours

Answer: (A)

In supervising station alarm systems, reporting any power loss without unnecessary delay is essential so responders can act quickly. Delaying power supply failure signals for more than 10 minutes would leave the monitoring station unaware of a fault for too long, which is not allowed because it undermines the system’s protective purpose. Transmitting power supply failure signals immediately on failure aligns with the expected rapid notification standard. The other scenarios describe configurations that don’t address the need for prompt reporting and would weaken continuous monitoring, but the specific prohibition here is the extended delay.
